UCC3819 Power Factor Preregulator

UCC3819 Description

ą D Controls Boost Preregulator to Near-Unity Power Factor D World Wide Line Operation D Over-Voltage Protection D Accurate Power Limiting D Average C.
The UCC2819/UCC3819 provides all the functions necessary for active power factor corrected preregulators.

UCC3819 Features

* such as lower start-up current, lower power dissipation, overvoltage protection, a shunt UVLO detect circuitry and a leading-edge modulation technique to reduce ripple current in the bulk capacitor. The UCC3819 allows the output voltage to be programmed by bringing out the error amplifier noninvert

UCC3819 Applications

* of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessari
